Specification of Application filed. June 2, 1819.

To all w 7mm it may concern:

Be itlznown that l, S'rannnr 'l. HARVEY, a citizen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful improvements in Advertis ing Display Devices, of which the following is a specification.

This invention relates to an advertising device of that class wherein a series of slidable panels carrying display advertisements are laterally mova le in front of and behind a corresponding series of fixed display advertisements, whereb periodic exposure of the fixed and movable advertisements is successively effected.

T he object of the invention is to obtain a maximum of advertisement exposure with a mechanism that is simple to construct and is economical in the motor power used.

The invention is particularly described in the following specincation, reference being made to the drawings which it is accon panied, in which:

Figure 1 is a front view of the device in perspective.

he fr; i work comprises two posts or styles 2 between which extend top and bottom cross rails 33 and i and intermediate c-is rails 5, dividing the framework into i-lliu'd horizontally disposed spaces.

The underside of the cross rail 3, the top of the hottoin rail 1, and the top and ltottoin of en intermediate rail 5, are lengthwise grooved as at 6, to receive movable panels 8, wl ich in the grooves of the cross rails and have small grooved wheels 9 adjacent each end to run on the edge of a rail 10, see Figs. 4: and 5, inserted along the middle of the top groove 6 of each cross rail 5 and 1. The length of these movable panels is approximately two-thirds of the length of the horizontally disposed. spaces between the side posts 2.

Letters Patentlatented Apr. 20, 1920.

Serial No. 301,303.

Down the front of the frame 2, 3, l, 5, is

;; scared a middle panel "I, the width of which pixoxii'nately one-third the space bethe side posts, and behind tl e plane grooves l5 liXed panels 11 are inserted which extend from each side post 2 to a osition in line with the adjacent edge of the middle panel 7.

On the faces of the middle panel T. both halves of the movable panels and the fixed side panels 11, are display aevertiseinents. 'lhosc on the middle panel 7 are constantly osed, while those on the faces of the stan onarv pa els .11 and movable panels 8 are alternately revealed and hidden as the panels 8 are moved from the one side to the other.

The movable panels 8 are disposed alternatelv to opposite ides of the frame and e 'ieriodicallv moved endwiseby a flexible dless line 12, preferably a sprocket chain, wnich from a sprocket 26 driven at a moderately slow speed from a motor or other suitable source of power, not shown, behind the panels and within the frame 2, 'i', This endless chain 12 passes arounc small sheaves 13, 14, 15, 16, 17, 18, 19, 20, 21, 2 2, 2e. 25, mounted in the cross rails 5 and such supplenientarv framing as may be necessary behind and in planes parallel to the face of the This chain 12 has in one place a pin 2? projecting from each side of it, which engages the sides of a double forked projection 28 secured to each panel.

by which the panels are carried successively from side to side of the frame.

The small sheaves around which the chain passes are arranged somewhat as shown, those 1%, 15, 16, 17, 18 being in one plane to engage the inner fork of each panel projec- A8, and those 21, 2 3, 2 1, 25, and the 26 are in an adjacent parallel plane e the outer fork of 28; 13 and 26 iediate guide pulleys. forked projections 28 are secured to elv the midlength of each slidthat side, so that the pin 27 of the chain 12 will freely leave its engagement with the fork member 28 as soon as the panel has been moved to its limit.

The other sheaves 1%f-.,16, 18, 21,23, 25 are a sufficient distance outside the edges of the middle panels 7 to insure that the projecting pin 27 of the chain 12 will engage the forked projections 28 of the movable panels.

As stated, the shaft on which the driving sprocket 26 is secured may be driven by any suitable means from any convenient source of power, preferably by a small electric motor, conveniently placed within the framework of the sign, the speed of which motor is reduced to that required.

The power required is very light as only one panel is moved at a time, and being mounted on wheels they require but a trifling amount of power to travel them from side to side.

Although a sprocket chain is used and has proven satisfactory, a flexible endless line of any kind will effect the desired object pro vided the panel engaging projection of the line, corresponding to the pin 27, be such that twist of the line will not prevent its proper engagement with the forked projection 28 of the movable panels.

With this construction as described and illustrated, a large amount of advertising space is rendered available, an amount quivalent to two-thirds in excess of the area inclosed by the sign frame. (if this available area four-thirds, comprising the fixed surfaces 11 and the movable surfaces 8, has the advantage of continual change, and two-thirds, comprising the movable panels 8, of change and motion, while the remaining one-third, the front middle panel 7, which alone is unchangeable, derives advantage from its proximity to the change able and moving areas.

/Vhile one oanel is in motion the others are at rest providing full opportunity for inspection of the advertising matter re vealed.

The sign is capable of considerable variation in" its application, from the smaller sizes adaptable to window display to the largest size of sign used. The sign may be double faced, that the seine mechanism mav operate at both sides.

In operation, assuming the upper and the lower movable panels 8 in Fig. 1 to be on the left of their runway, and the intermediate panel 8 to be on the right, the projecting pin 27 of the chain 12 as it passes over the sheave 1 1 will engage the inner fork of the projection 28 of that panel and will carry the panel across to the right, where at the limit of its movement the chain 12 and its pin 27 will turn downward over the sheave 15 and around the sheave 16 where the pin 27 will encounter the inner fork of the projection 28 of the next movable panel below and will carry it to the left. Turning downward over the sheave 17, it will leave that panel on the left and passing around the sheave 18 will engage the inner fork of the projection 28 of the bottom panel and will carry it to the right, disengaging from the projection as the ehain passes upward around the sheave 19. All the panels 8 have thus been moved across to their opposite side.

The chain 12, as it passes over the sheave 19 to the sheave 21 over the intermediate sheave 20, is diverted from the plane of the inner fork of the projection 28 to that of the outer fork, and as the projecting pin 27 of the chain passes around the sheave 21 it engages the outer fork of the projection 28 of the upper panel and moves it from right to left disengaging from it as it passes downward over the sheave 22. As it passes around the sheave 23 it will engage the outer fork of the next panel below and will move it from left to right, disengaging from its projection 28 as it passes downward over the sheave 24, and passing around the sheave 25 the pin 27 will engage the outer fork of the projection 28 of the bottom panel and move it from right to left, disengaging from it as it passes around the sprocket 26 from which the chain derives its movement. This completes the cycle of movement, all the panels 8 having been moved across to the other side and back.

Care must be taken in arranging the position of the sheaves 15, 17 19, 22, 241 and the driving sprocket 26 that the pin 27 of the sprocket chain will free itself from engagement with the forked projection 28 of each panel as that panel reaches the limit of its movement.

Having now particularly described my invention, I hereby declare that what I claim as new and desire to be protected in by Let ters Patent, is:

1. An advertising device, comprising the combination with a suitable frame supporting fixed display surfaces in adjacent par-- allel planes, the adjacent edges of which surfaces are in line with one another, cross rails between these vertically disposed surfaces dividing them into horizontally disposed groups, a panel endwise movable along the cross rails between the surfaces of each group, and means for successively moving the panels of adjacent groups in opposite directions whereby the'display surfaces of the movable panels and of the surfaces which they move in front of, are alternately hidden and revealed.

, 2. An advertising device comprising, the combination with a suitable frame supporting three vertically disposed display surfaces in adjacent parallel planes, the middle one being in front of the two side ones with the adjacent edges in line with one another, cross rails between these vertically disposed surfaces dividing them into horizontally disposed groups, a panel mounted to move along each group between the surfaces, the length of each movable panel being approximately equal to twice the width of the vertically disposed surfaces, and means for successively moving each panel from one side to the other to project that end of each that was behind the middle front surface in front of the exposed face of the side one behind and to reveal the surface of the other side.

3. in advertising d vice, comprising the combination with a suitable frame support ing three vertically disposed display surfaces in adjacent parallel planes, the middle one being in front of the two side ones with the adjacent edges in line with one another, cross rails between these vertically disposed surfaces dividing them into horizontally disposed groups, a panel mounted to move along each group between. the surfaces, the length of each panel extending across the width of one of the side display surfaces to the opposite edge of the middle surface, and means for successively moving the slidable panels of the adjacent groups in opposite directions.

4:. An advertising device, comprising the combination with a suitable frame supporting three vertically disposed display surfaces in adjacent parallel planes, the middle one being in front of the two side ones with the adjacent edges in line with one another, cross rails between these vertically disposed surfaces dividin them into horizontally disposed groups, a panel mounted to move along each group between the surfaces, the length of said panel extending across the width of one of the side display surfaces to the opposite edge of the middle display sur face, and an endless flexible line traveling over sheaves, said line having an enlargement that will engage a projection from each of the movable panels and move them successively from side to side.

5. An advertising device, comprising the combination with a suitable frame supporting three vertically disposed surfaces in adj acent parallel planes, the middle one being in front of the two side ones, cross rails between these vertically disposed surfaces dividing them into horizontall disposed groups, a panel slidably mounted to move in grooves of the cross rails along each group,

the length bf the panel extending across the width of one of the side display surfaces to the opposite edge of the middle one, an endless sprocket chain traveling over grooved sheaves disposed on each side of the middle surface to carry the chain parallel with the cross rails to move in opposite directions in adjacent groups, said chain having a projection to engage a corresponding projection from each panel, and a sprocket wheel for moving the chain.

6. An advertising device, comprising the combination with a suitable frame supporting three vertically disposed display surfaces in adjacent parallel planes, the middle surface being in front of the two side ones, cross rails between these vertically disposed surfaces dividing them into horizontally disposed groups, the adjacent edges of each cross rail being grooved, panels endwise movable on roller wheels in the grooves of the cross rails along each group, the length of each panel extending across one of the side surfaces to the further edge of the middle surface, an endless chain passing around sheaves mounted adjacent the vertical edges of the middle surface to move parallel with the cross rails in opposite directions in adjacent groups, said chain having a pin projecting from each side to engage a corresponding projection in each movable panel, and means for endwise moving the chain.

7. In an advertising device, the combination with a suitable frame supporting fixed display surfaces in adjacent parallel planes, said frame including a top and a bottom cross rail, a panel endwise movable along the cross rails and of a length to extend over approximately two-thirds of the display surfaces, means for successively moving the panel back and forth endwise whereby to first expose one section of the panel and one of the fixed display surfaces and then expose another section of the panel and another of the fixed display surfaces accordingly as the panel is moved in one direction or the other, said moving means comprising a single flexible line passing over sheaves and moving unidirectionally with provisions for engaging said movable panel to automatically move it first in one direction and then in the opposite direction substantially as shown and for the purpose described.

In testimony whereof I aiiix my signature.
